RELATED APPLICATION

The present application is a divisional application of U.S. application Ser. No. 16/050,916 filed Jul. 31, 2018, which claims the benefit of U.S. Provisional Application No. 62/539,119 filed Jul. 31, 2017, which is hereby incorporated herein in its entirety by reference.

TECHNICAL FIELD

The present disclosure relates to portable fabric display panels mountable on a collapsible frame for displaying graphical images, and more particularly to universal hub assemblies for attaching multiple graphic systems onto a single collapsible frame.

BACKGROUND

Many different display systems which are both portable and collapsible are known to those in the art. These systems typically include a scissors frame assembly having a plurality of elongate arms attached at their ends to hubs which enable the frame to transition between a collapsed, storage position and an expanded, display position. Such systems are commonly used for sales and/or trade show purposes, as they are lightweight and can readily be collapsed into a fraction of its display position size for ease in transportation.

FIGS. 1A-1C depict a first portable display system 100 of the prior art. The portable display system 100 can include a pop-up scissors frame 101 comprising an array of box frames 102, wherein the edge of each box frame 102 is defined by a pair of crossed elongate arms 104A-104B. Each of the elongate arms 104 is pivotably coupled to a hub 106 at its respective end. Opposing hubs 106A, 106C, defining one corner of the box frame 102, can be held apart in the display position by a cross member 108A.

The respective edges of adjacent box frames 102 can share pairs of crossed elongate arms 104 along a common border. Accordingly, as depicted, a hub 106A located on a corner of the perimeter of the first portable display system 100 is operably coupled to two elongate arms 104A, 104C and one cross member 108A. A hub 106B located along an edge of the perimeter of the first portable display system 100 is operably coupled to three elongate arms 104B, 104D, and 104E, and one cross member 108B. A hub 106E located interior to the perimeter of the first portable display system 100 is operably coupled to four elongate arms 104E, 104F, 104G, and 104H, and one cross member 108C. Other configurations of the first portable display system 100, including configurations other than an array of nine square box frames 102 are also possible.

As depicted in FIG. 1B, the outwardly facing surface 110 of the hub 106 can have a convex or curvilinear shape, having a knob or post 112 extending therefrom. As depicted in FIG. 1C, a stretchable fabric 114 can be operably coupled to the post 112, for example by a buttonhole 116 defined within each corner of the fabric 114. As depicted in FIG. 1A, when the buttonholes 116 are attached to the respective hubs 106, the fabric 114 stretches, so as to cause the sides of the fabric 114 to appear to arch inwardly.

FIG. 2A-2B depict a second portable display system 150 of the prior art. Like the previous example, this portable display system 150 can include a pop-up scissors frame 151 comprising an array of box frames 102 including a plurality of hubs 117. However, instead a plurality of stretchable fabric panels attached to the hubs 117, a sub-frame 118 configured to support a single large fabric panel 120 is attached to the outer perimeter of the display system 150.

As depicted in FIG. 2B, the frame 118 can define a channel 122, and fabric panel 120 can include an edge 124 configured to fit within the channel 122. With the edge 124 securely positioned within the channel 122, fabric panel 120 can be stretched across the frame 118 for display. In some examples, commercially referred to as a Silicon Edge Graphics (SEG) frame, the edge 124 can further include a layer of silicone, which in combination with the elasticity of the fabric panel 120 can aid in the retention of the edge 124 within the channel 122. One advantage of the single fabric panel 120 is that the edges of the fabric panel 120 do not arch inward like the fabric panels 114 of the first portable display system 100; accordingly, the image on the single fabric panel 120 is not distorted during display.

Presently, the hubs 106 of the first portable display system 100 are not compatible with the frame 118 of the second portable hub display system 150; that is, the frame 118 cannot be mounted to the hubs 106 of the first portable display system 100. Likewise, the hubs 117 of the second portable display system 150 do not include knobs or posts 112 for connection to the buttonholes 116 of the stretchable fabric 114 of the first portable display system 100. Moreover, the hubs 106, 117 are not interchangeable between the first and second portable display systems 100, 150. Therefore, users who wish to utilize a multiple panel display system must purchase one display system 100, while users who wish to display a single large panel must purchase a second, separate display system 150.

Accordingly, what is needed in the industry is a single portable display system capable of displaying both a plurality of stretchable fabric panels, as well as a large framed panel.
